Abstract

An analysis of non-linear I-V conduction characteristics in three different insulating liquids was conducted in the present paper. Apparent mobilities of the charge carriers and the magnitude of energy barriers at the metal liquid interface were derived for these liquids which include mineral transformer oil, Diala D oil and Midel 7131 synthetic ester liquid. It has been shown that I-V characteristics for thesde liquids demonstrate a non-linear behaviour with three possible regions: Ohmic conduction, space charge saturation regime and Fowler Nordheim charge injection.
